RAILWAY-SWITCH.

SPECIFICATION forming part of Letters Patent No. 543,605, dated uly 30,1895.

Application filed June 8, 1895'. Serial 1%: 552,112. (No model.)

To all whom it may concern:

Be it known that I, AXEL A. STROM, a citizen of the United States,residing at Austin, in the county of Cook and State of Illinois,

have invented a new and useful Improvement in Railway-Switches, of whichthe following is a specification.

My invention relates to an improvement in the class of point-rail orsplit switches; and it relates, more particularly stated, to improvedmeans for adjusting at will the throw of the point-rails through themedium of a tie-bar connecting them by moving the tie-bar backward orforward with relation to the points to spread the rails farther apart orbring them closer together, as the nature of the adjustment required maydemand. To this end I provide an adjustment-plate, preferably one oneach point-rail, though it might be atone or each end of the tie-bar,having provided upon it an adjustment-line either in the form of a slot,a flange, or a series of holes, or the like, in inclined relation to theline of the main rail, whereby when either end of the tie-bar is movedalong the inclined line of adjustment and fastened at any desired pointthe adjacent point-rail will be set nearer to or farther from theadjacent main rail, depending on the direction of the line in which thetie-bar end is moved.

Referring to the accompanying drawings, Figure 1 is a plan view ofasection of railway-track containing a split switch provided with myimprovement; Fig. 2, a section taken, at the line 2 on Fig. 1 and viewedin the direction of the arrow, and Fig. 3 an enlarged perspective Viewof a point-rail end provided with my improved adjustment-plate.

A A are the main rails, and B B the pointrails, the latter beingconnected by a tie-bar G at any desired portion of their length,preferably near their points. The connection is made through the mediumof plates D D, shown as placed and permanently fastened opposite eachother adjacent to the slideplate E, one on the inner side of eachpointrail and conforming to the web to which it is bolted and flange ofthe rail, beyond which latter it extends, being provided along the outeredge of its extended portion with a line of holes inclined to the lineof the adjacent main rail. As represented, the plate D is represented asoblique along its outer edge to extend parallel with the inclinedadjustmentline 1'; but, of course, it might be parallel with the rail B,on which it is secured. Where the tie-bar engages a plate D it is shownto be provided with a clip q to receive between it and the bar, (both ofwhich are coincidently perforated) the edge of a plate and cause a hole'1" in the latter to coincide with such perforations and permit a pin 19to be passed through the three coinciding holes to fasten the tie-barand plate together.

According to the construction shown, if the tie-bar be moved at eitherend along the line of holes r toward the flaring end of the adjustment-plate D the adjacent point-rail will thereby be adjusted closerto its main rail, and it moved in the opposite direction the adjus'tmentwill separate the point-rail farther from its main rail, and, ifdesired, and the conditions require, the tie-bar may be movedsimultaneously at both ends to eifect the adjustment of both point-railsthrough the medium of the plates D.

Without departing from the principle of my invention, the essentialfeature of which is an adjustment-plate provided with an adjustment-line inclined to the line of the main rails for adapting thetie-bar by setting it in the manner described to produce the pointrailadjustment, as explained, the construction may be variously modified asto details and the particular combination of parts. Hence I do not limitmy invention to such particular details and combinations.

What I claim as new, and desire to secure by Letters Patent, is

1. In combination with a split-switch and the point-rail connecting-bar,an adjustmentplate provided with an adjustment-line inclined to the lineof the main-rail, for connection of the bar with a point-rail,substantially as and for the purpose set forth.

2. In combination with a split-switch and the point-rail connecting-bar,adjustmentplates one at each end of said bar and each provided with anadjustment-line inclined to the line of the main-rails for connection ofI00 the bar with the point-rails, substantially as and for the purposeset forth.

3. In combination with a split-switch and the point-rail connecting-bar,an adj ustmentplate fastened to a point-rail to extend at its inner sideand provided with an adjustmentline inclined to the line of themain-rail for connection of the bar with the point-rail, substantiallyas and for the purpose set forth.

4. In combination with a split-switch, the point-rail connecting-barprovided near its opposite ends with clips, and adjustmentplates securedto the point-rails to extend at their inner sides and each provided withan adjustment-line inclined to the line of the 1nain-rails and adaptedto be connected with AXEL A. .S'IROM. In presence of i J. II. LEE,

J. W. DYRENFORTH.
